Methods and apparatus for determining the total flow rate of gaseous fluid passing through a plurality of conduits utilizing a plurality of total and static pressure sensing probes, the number of total pressure sensing probes being selected and deployed within each conduit to cover cross-sectional areas of substantially equal and corresponding size, each total pressure sensing probe being connected to one central pressure averaging manifold and each static sensing probe being connected to a second pressure averaging manifold, the pressure difference between the two pressure averaging manifolds being compared to determine the pressure difference as a measure of average velocity. In addition, the fluid flow to and from each manifold is controlled, as by means of a restriction, to impede the flow while providing a substantially laminar flow and a Reynolds number less than 4,000.
